Application filed November 15, 1915. Serial No. 61,605.

To all whom it may concern:

Be it known that 1, WILLI M GoonnLL, a citizen of the United States,residing at Millinoclret, in the county of Penobscot and State ofMaine,have invented certain new and useful Improvements inPaper-Pulp-Lap- Folding Machines; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

The invention relates to a paper pulp lap folding machine.

The object of the present invention is to provide a simple, practical,and comparatively inexpensive paper pulp lap folding machine adapted toreceive the sheets or laps of paper pulp as the same are discharged froma wet machine and equipped with a roller bed for. receiving the paperpulp lap and with means operating in timed sequence for successivelyfolding the sheets of paper pulp or laps to the required size wherebyhand folding as now practised in paper pulp mills may be entirelyeliminated.

lVith these and other objects in view the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings and pointedout in the claims hereto appended, it being understood that variouschanges in the form, proportion and minor details of construction may beresorted to without departing from the spirit or sacrificing any of theadvantages of the invention.

Like numerals'of reference designate corresponding parts in all thefigures of the drawings.

In the accompanying drawings, in which is illustrated the preferredembodiment of the invention, the paper pulp lap folding machinecomprises in its construction a main frame 1 of substantiallyrectangular form and of any desired construction and provided withsuitable bearings for a pair of spaced transversely disposed shafts 2and inner and outer longitudinally disposed shafts 3 and 4 arranged inpairs as clearly illustrated in Fig. 1 of the accompanying drawings. Theshafts 2, 3, and t are provided at intervals with arms 6 and 7 and theyconstitute folding devices for successively folding a sheet or lap ofpaper pulp. The folding devices are oscillated in timed sequence ashereinafter fully described. The shafts 2 are located in a horizontalplan slightly above the shaft 4 while the intermediate longitudinalshafts 3 are located slightly below the plan of the shafts 4. The arms 7have angle bonds 8 to arrange their terminal portions 9 at right anglesto the body portions of the rods as shown. The transverse shafts 2 areprovided with central offset bends 10, which are adapted to lengthen thedischarge hole 11 hereinafter described so that the folded lap may fallthrough without clogging at the ends and the intermediate longitudinalshafts 3 are located at the ends of the bends 10 which extendoutwardlyas shown in Fig. 1 when the folding devices are in their normalor initial position. By this arrangement an open oblong space 1.1 isformed at the center of the folding machine. The sheets of paper pulp,which are approximately six feet square, when folded are discharged atthe central open space. The shafts 2 are successively operated to fold asheet of paper pulp transversely along the lines of the shafts .2 whichare spaced approximately equidistant from each other and from theends ofthe machine.

The outer longitudinal shafts at are then operated simultaneously tofold the sheets longitudinally along the lines of the said shafts 4,after which the intermediate or inner longitudinal shafts 3 aresimultaneously operated to fold the sheets centrally and cause thefolded sheets to fall through the open space 11. The paper pulp lapfolding machine is equipped with a roller bed composed of end andintermediate sections, the rollers 12 of the end sections being mountedin stationary bearing brackets 13 or other supporting means and therollers ll of the intermediate section being mounted in bearings orsuitable supports 15 andcarried by,

a vertically movable frame 16 operatedin timed sequence withrthe foldingdevices and adapted to be elevated to the plane ofgthe rollers of theend section when a sheet of paper pulp is deposited on the machine andlowered out of the way of the folding devices after the sheet has beenarranged on The rollers project slightly the machine. above the plane ofthe arms of the folding devices and the rollers ll of the inter-me diatesection of the roller bed are carried downwardly below the plane of thearms of the said folding devices and out of the way of the same so thatthe paper pulp may be folded in a flat condition without the foldticallymovable frame is connected by links orrods 20 with crank elements 21 and22 of an overhead transverse shaft 23. The lower ends of the links orrods 20 are connected with the horizontal pins 19 and the crank elements21 and 22 of the crank shaft 23 while being shown in the form of simplecranks may be of any other form as will be readily understood. The crankelement 22 is eccentrically connected with a stop-wheel 24 mounted onthe inner end of a horizontal shaft 25 which has a slidingclutch-section 26 for engaging a clutch face 27 of a sprocketwheel 28whereby when the clutch section is engaged withthe sprocket wheel, theshaft 25 will be rotated to actuate the vertically movable frame. Theclutch section 26' may be slidably interlocked with the shaft in anydesired manner audit is connected with'an upwardly extending arm 29 ofanapproximately T-shaped lever 30 fulcrumedatits angle and havinginwardly and outwardly extending horizontal arms 31 and-32. Thestopwheel 24- is providedat diametricallyopposite points withnotehes orrecesses34 of substantially semi-circular: shape to enable the arm 31 ofthe lever 30 to engage \vith the said notches 3 1 and to be readilydisengaged therefrom. The upwardly extending arm 29 is connected with acoiled spring-35 secured to the main frame or other suitable support andadapted to maintainthe clutch section 26 normally out of engagement withthe sprocket wheel '28 and also hold the outer arm 32 of the T-shapedlever 30 against a flange or rim 36 of a cam gear wheel 37. The "cam"gearwheel 37 which is-preferably in the form of a sprocket wheelisprovided-at the annular flange or rim 36"-With cams 38 and 39 arrangedto suecessively engage the arm 32 ofthe T-shaped lever-30 to move thearm- 31out of engagement with the stop wheel and simultaneously carrythesliding clutch seetion into engagement with'theiclu-tch face 27 of thegear wheel 28 whichpis preferably in the form of a sprocket wheel and Ywhich is continuously rotated by the meanshereinafter described.

This operation of the T-sha-ped-lever rotates the-shaft 25 and the stopwheel 2% which :maintains the lever 31 out ofengagement-with the notches3 1 until the next notch is carried toa point above the arm 31. Theshaft 25: is rotated during this time by the engagement of theclutchsection or men1- bers. As soon as the stop wheel 2st has made one-half arevolution, the. other notch or recess 3 1 is carried to a positionabove the arm 31 which is moved into the notch 3% by'the spring35ithereby withdrawing the clutch section 26 from engageinentwith theclutch face 27 of the sprocketwheel 28 and stopping the shaft 25. Thishalf revolution of the wheel 2% and the shaft. 23 elevates themovablesection of .the roller bed which remains in an elevated position. whilethe. pulp sheet is being transferred to the folding machine. hen thisoperation. has been. effected the wheel 37' through its cam 39 againoperates the T- shapedlever-and permits another half revolution. oftheshaft:23zwhich lowers the movable section of the roller bed from itselevated position to its position below the folding.devices.i In orderto provide an easy movementofthe. frame 16, the movable section of theroller bed is counterbalanced by suitable weights lOconnected with oneend of a cable 41 orother suitable flexible con nections which-isarrangedon an overhead pulley 4:2 and which is connected at its otherend with the frame. 16 .at the center of the transverse member 18'.

Any other suitable means may of course be employed for counterbalancingthe ver ticallv-movable sectionofthe roller bed and for. securingxaneasy operation thereof in moving the. same to and from the horizontalplane of the stationary sections.

Each ofv the transversely disposed shafts 2 of the folding devices isequipped at one opposite direction to return them to their initialposition. The stop wheel 47 is provided with a single notch or recess 48and it is mounted on a shaft 49 having a slidable clutch section 50adapted to engage a clutch face 51 of a sprocket wheel 52. The slidablesection is connected with a T-shaped lever- 53 constructed similarly tothat heretofore described and adapted to coijperate with the stop wheel47 and with a cam wheel 54 having a single cam 55 on its annular flangeor rim 56. The wheel 54 is in the form of a sprocket wheel similar tothe cam wheel heretofore described and the cam of the cam wheel 54 ofthe two transverse shafts 2 is timed to secure a proper operation of thefolding devices to successively fold the sheet of pulp from the ends ofthe machine over the central portion as before described. The T-shapedlever 53 is connected with a coiled spring 57 which operates similarlyto that heretofore described in moving the T- shaped lever into thenotch of the stop wheel and withdrawing the sliding clutch from thesprocket wheel 52. The outer longitudinal shafts 4 are provided at oneend with pinions 58 which mesh with rack bars 59 operating in suitableguides and connected by rods 60 and 61 with crank elements 62 and 63 ofa crank shaft 64 having an extension 65 on which is mounted a slidableclutch section 66 adapted to engage a clutch face 67 of a sprocket wheel68. The slidable clutch section is operated by a T-shaped lever 69controlled by a cam Wheel 70 and a stop wheel 71. The stop wheel 71which is constructed similar to. the stop wheel 47 is mounted on theshaft 64 and the cam wheel 70 which is similar in construction to thecam wheel 54 is mounted on a shaft 72. The cam wheel 7 O is timed tosecure a proper operation of the folding devices with which it isconnected.

The inner or intermediate longitudinal shafts which effect the finalfolding and the discharge of the folded sheets of paper pulp areprovided with intermeshing gears 74, 75 and arm 76 being connected withthe gear 74 and with the shafts 3 on which such gear is mounted andadapted to be oscillated for simultaneously rotating the said shafts 3.The arm 76 is connected by jointed rods or members 77 and 7 S with acrank 79 of a shaft 80 carrying a stop wheel 81 of mechanism 82 having asprocket wheel 83 and a cam sprocket wheel 84 and constructed similar tothe mechanism for operating the vertically movable rack bars heretoforedescribed. The cam of this mechanism is properly timed and when themechanism is operated the arm 76 will be oscillated and the innerlongitudinal rock shafts 3 will be simultaneously operated to effect thefinal fold of the paper pulp sheet and the dis charge of the latterthrough the space 11.

The actuating sprocket wheels of the several sets of mechanism and thecam sprocket wheels of the same are arranged in two horizontal rows asclearly illustrated in Fig. 3 of the drawings and are connected bysprocket chains 85 and 86 which are also arranged on driving sprocketwheels 87 and S8.

The driving sprocket wheels 87 and 88 are connected by sprocket gearing89 properly proportioned to regulate the speed. of the cam wheels abovementioned and time their operation when suitably arranged on thesprocket chain 86.
